...does anybody know if they still allow you to ride the large lake next to the MIA Airport?? (south of the 836) I know you were able to in years past, but what about now?

That was the spot back in the day before 2010..More then a dozen ski's on any saturday or sunday around the lake..
Now its a little bit slower because there's a cop boat and the hole area in front of the ramp is a manatee zone so watch out with the car cops also. but there is a ramp which is $6 on nw 7 street and about 51 ave i think. \
That lake connects with alot of things for miles and its a nice ride also.
